237cf456fd feat(gallery): galleries published as OCI artifacts (#12167)
* feat(oci): pull ORAS artifacts into a directory

Galleries published to an OCI registry arrive as an ORAS artifact whose
layers carry their tree path in org.opencontainers.image.title. Nothing in
pkg/oci could read a non-image manifest, so add PullArtifact: it lays the
layers out under a destination directory and returns the manifest digest so
callers can pin and verify signatures on it.

A registry is remote input and this writes files, so the manifest is
validated before any byte is fetched. A title that is absolute, escapes the
destination or is missing is refused, an artifact of an unexpected
artifactType is refused, and both the layer count and the total size are
capped with caller-settable limits.

* feat(gallery): fetch and verify galleries published as OCI artifacts

A gallery whose URL is oci://host/repo:tag is now pulled as an ORAS
artifact and its index.yaml read from the unpacked tree, alongside the
existing HTTP and file sources. Mirrors, the per-candidate timeout, the
failure cooldown and the last known good copy work the same for both
schemes, so a gallery can mirror an OCI primary with an HTTP fallback.

When the gallery declares a verification policy the artifact reference is
resolved to its manifest digest, the publisher signature is checked
against that digest, and only then is the same digest pulled. Nothing
unverified is written to disk or parsed. With strict integrity mode on,
an OCI gallery without a verification policy is refused instead of
warned about, which is what the flag already does for backend installs.

The pull lands in a staging directory that is renamed into the cache only
once the whole tree is on disk and the index reads back as an index, so a
failed or interrupted pull leaves nothing a later fetch would serve. A
fetch that finds a fresh cache entry does not contact the registry.

* feat(gallery): resolve entry urls relative to the gallery root

A gallery published as a self-contained tree, which is what an OCI
gallery is, names its base configs by their place in that tree. Such a
url reached the HTTP client verbatim and no entry of the gallery could
be installed.

A scheme-less entry url now resolves against the root the index came
from: the unpacked artifact for an oci:// gallery, and the directory of
the index URL otherwise. The relative path may not climb out of that
root, reusing the guard the artifact puller already applies to layer
titles, and an entry that does is dropped from the listing rather than
failing the whole gallery. An entry that names its own scheme is
untouched, so .ref indirection and local github: resolution behave as
before.

Reading an entry of an OCI gallery also needs the unpacked artifact
directory as its trusted root, since the cache is deliberately a sibling
of the models directory the downloader otherwise confines a file read
to.

* fix(oci): restrict artifact file permissions

Create artifact files with owner-only permissions to satisfy G302.
Document the existing path validation for the G304 scanner finding.
Check the permissions of downloaded layers in the artifact test.

* fix(oci): confine artifact writes to their root

Use root-relative filesystem operations to reject escapes through existing
directory symlinks. Retain owner-only permissions and add a symlink escape
regression test, without suppressing the path traversal finding.

* fix(credentials): keep secrets out of match and YAML parse errors

A match that fails to parse is no longer quoted in the Parse error, since
it may be a URL with a token in it. Userinfo is detected before the scheme
check, so ftp://user:token@host is refused as userinfo, and a match with a
query string or fragment is refused because it can never apply and a query
string is where signed URLs carry their token. Every YAML decode error is
now redacted, not only type errors: quoted scalars such as a secret under a
mismatched !!int tag are replaced and unquoted map keys are cut off.

* fix(downloads): make auth errors name the real cause and never retry unresolved secrets

AuthError now appends its cause, so a registry's DENIED or UNAUTHORIZED
detail reaches the operator. HTTP auth errors print only the status text in
place of the cause, because the downloader builds that cause from the
requested URL, which can carry a signed query string. Registry pulls say
that docker config credentials were tried too, and a download that carried
a caller-provided credential (WithBearerToken, or an explicit authorization
on gallery reads) reports that credential as rejected instead of blaming
the store.

The Range probe for a leftover partial file now returns an unresolved
secret as a permanent error, like the download request already did.

* fix(credentials): keep oras pulls anonymous on a broken docker helper and close bodies

When docker config names a credsStore helper that cannot run, the oras
credential func now logs at debug and returns no credential, so public
pulls keep working as they did before the adapter existed. The transport
closes the request body when a rule's secret cannot be resolved, as the
RoundTripper contract requires. The redirect spec now uses a custom header
rule on the origin, which net/http would not strip on its own, to prove the
transport does not carry credentials to the next hop.

* test(oci): cover FetchImageBlob authentication against a private registry

FetchImageBlob now has a spec that pulls a layer blob by digest from a
basic-auth registry through the oras credential adapter, and one that shows
the same fetch fails when no rule matches. oras only speaks HTTPS here, so
the registry serves TLS and the spec points http.DefaultTransport, which
retry.DefaultClient falls back to, at the test server's client for its
duration instead of adding a transport seam to production code.

* docs(credentials): document auth error wording, ollama manifests and registry tokens

The errors section now lists the registry and provided-credential messages
and says the server's reason is appended. ollama:// manifests are fetched
without credentials, so only blob downloads use the file. GHCR, Docker Hub
and Quay need basic auth with the token as password, and match rules must
not carry a query string or fragment. The backend gallery docs and the
container troubleshooting section now point to the private sources page.

* fix(credentials): document trusted file path

The credentials path comes from operator configuration. Mark the file
read with a scoped G304 explanation to resolve the gosec false positive.
